In this photo you can see the chain like segments along the edges of the layers.They look like single cell organisms that are building the host rock like on a coral reef. Perhaps, those bead like spheres are organisms laying the cell eggs that produce the rock that they can form in, and later drop out of, and start the process over again. Dead now and fossilized.

Or then again, they could just be how the rock has eroded and weathered. Eddies in wind/sand storms formed protuberances that were then smoothed out into dome-like features.

I agree eddy currents in the air or even water could scoure out such formations individually. However, if you look at them more close they are linked together in long chain like strings of beads. When fossils remineralize they are made from different elements from which they started from. Different elements erode at different rates. If this base material is all the same then it should erode at the same rate. If some material is harder in the mohs scale within the base material it would errode slower than the surrounding material. With the shifting wind conditions on Mars I would think the errosion rate is not constant at any given point.
